The area of the knees is built in stretch and horizontal partitions to bend the knees, sleep on your side or sit in tailor easily but without loss of heat.
The very enveloping hood is lined with an oversized collar, attached by velcro to completely block the cold at the neck.
The bag is contoured to the hips and then straight up the Foot Box to offer a comfortable volume. OffBeat and stocked for an effective thermal seal zipper does not let through the cold.
